Looking for Chevy car and truck Parts.

I have a 1965 Chevy II Nova. I am missing a few parts. I need the headlight assemblies that the light itself bolts/screws into. I got my car from a junk yard and I had rust issues in the wheel wells. Mine are not usable due to the bad rust and they don't remanufacture those. I also am trying to find another factory steering column. mine is busted on the inside and I have no idea on rebuilding it.

For my 1984 Chevy C10,its my daily driver and I am also working on making it a drag truck. I'm looking for cheap usable slicks on Chevy wheels. I don't have over $400 to blow on tires and am hoping to get a cheap pair of used slicks. don't care what make. I am also looking for a suggestion for a 4 point racing harness. I don't have bucket seats, I have a bench seat and I am planning on keeping it since its also my daily driver.

If you have any information please let me know.Thanks and God Bless, Sam Ruppert
